WARNING - THIS UNIT USES R290, A HYDROCARBON, PROPANE REFRIGERANT THAT IS
ENVIRONMENTALLY FRIENDLY BUT IS ALSO HIGHLY FLAMMABLE AND EXPLOSIVE. PLEASE
READ THIS MANUAL CAREFULLY AND FOLLOW ALL SAFETY PRECAUTIONS CONTAINED HEREIN
TO AVOID THE RISK OF FIRE OR EXPLOSION. FAILURE TO FOLLOW THE SAFETY PRECAUTIONS
MAY RESULT IN SERIOUS INJURY, OR DEATH, AND/OR PROPERTY DAMAGE.
This section applies to R290 Hydrocarbon units only. To identify the refrigerant type,
see the data plate in the cabinet interior.

Hydrocarbon Guidelines 2
PROPANE (R290) IS HIGHLY APPROVED FOR USE AS A REFRIGERANT IN COMMERCIAL,
SELF-CONTAINED UNITS IN THE US UNDER LIMITED USE CONDITIONS. IT CAN ONLY BE
USED IN NEW EQUIPMENT. BACKFITTING OR MODIFICATIONS OF OLD EQUIPMENT ARE
NOT ALLOWED. IT MUST BE CHARGED IN A STRICTLY LIMITED VOLUME OF UP TO 150
GRAMS (5.3 OZ) PER REFRIGERATION CIRCUIT. EVEN THOUGH THIS IS A SMALL AMOUNT,
IT STILL PRESENTS A FIRE OR EXPLOSION HAZARD IF IT LEAKS OUT OF PARTS THAT
HOLD REFRIGERANT. WHEN IT COMES IN CONTACT WITH AIR, A FLAMMABLE PROPANE-AIR
MIXTURE CAN BE CREATED AND EASILY IGNITED BY ELECTRICAL SPARKS, OPEN FLAMES OR
HOT SURFACES. THE RISK IS HIGHER IN SMALL, CONFINED, POORLY VENTILATED SPACES.
PROPANE WILL SETTLE AT LOWER ZONES BECAUSE IT IS HEAVIER THAN AIR. TO REDUCE
THESE RISKS, OBSERVE THE FOLLOWING PRECAUTIONS
• Avoid installation of unit in areas with open flames or in general vicinity of open flames or high
surface temperatures.
• Avoid unit installation in small, confined spaces. Ensure ample ventilation at all times. Keep all
exhaust vents free of any blockage or obstruction.
• Do not rely on smell to detect potential leaks of propane refrigerant. Propane refrigerant is a
high purity propane gas and does not contain odorants or stenching agents. These additives are
typically used in fuel-grade propane and natural gas in order to give them a distinctive smell which
makes it easier to detect leaks.
• General service and repairs must be performed in well-ventilated areas.
• General service and repairs must be performed only by professionals authorized by Everest
Refrigeration.
• Component shall be replaced with Everest-issued, like components to minimize the risk of possible
ignition resulting from incompatible parts or improper repairs.
• Do not modify, re-appropriate, or remove any functional part(s) from the unit.
• Handle the unit with care to avoid any damage.
• Practice safety guidelines when transporting the unit. Consult with your local Department of
Transportation for requirements in moving flammable gasses.

3Installation Instructions
Installation Instructions
1. Inspect for any freight damage upon delivery
of the unit. If damage is detected, immediately
report it to an Everest representative. Ever-
est is not responsible for damage that occurs
during shipment.
2. Keep the unit upright at all times. The com-
pressor contains oil, refrigerant, lubricants,
and various chemicals. When tilted, these flu-
ids may shift and travel to sections where they
don’t naturally occur. This will lead to system
contamination and compressor failure.
3. Some units require caster installation for
proper performance. Visit our website at
www.everestref.com and enter your product’s
model number in the search field to determine
its caster requirements.
4. Do not place your hands under the unit when
moving it to avoid injury from sharp edges,
protruding parts or weight impact.
5. Select a location with good air ventilation.
Poor ventilation rapidly increases ambient
temperature. High ambient temperatures
exceeding 86°F (30°C) promote excessive
compressor activity in order to maintain the
desired cabinet temperature. This will result in
decreased performance, advanced component
failure and the risk of fire.
6. Select a location away from heat-generating
equipment such as stoves, ovens, etc. Heat
sources rapidly increase the temperature of
the immediate vicinity. High temperatures
exceeding 86°F (30°C) promote excessive
compressor activity in order to maintain the
desired cabinet temperature. This will result in
decreased performance, advanced component
failure, and the risk of fire.
7. A distance of 6” is required for backside clear-
ance. This ensures proper ventilation and pre-
vents overheating which can lead to advanced
component failure and the risk of fire.
8. Select a location with a hard, leveled surface.
Use a leveling tool on the unit to ensure proper
alignment. Proper door function and condensate
removal is dependent on accurate balance. In-
stall the front leg stabilizers for units that come
standard with it to ensure proper door functions
and unit stability.
9. Select a location close to an electrical wall out-
let to ensure direct connection without the use
of extension cords.
10. Select a location away from severe moisture
conditions. This may compromise the unit’s
electrical components and lead to electrical
shocks or the risk of fire.
11. Select a location that will not expose the unit
to extremely dusty conditions. Environments
with high dust and debris content will signifi-
cantly hasten condenser coil blockage and will
result in decreased performance, advanced
component failure and the risk of fire.
12. Do not build an enclosure or cabinet around
the unit. This will restrict air ventilation result-
ing in elevated compressor activity, decreased
performance, advanced component failure and
the risk of fire.
13. The unit is not intended for use in food trucks.
Limited space, lack of ventilation, and ambient
temperatures exceeding 86°F (30°C) typical to
this setting will result in elevated compressor
activity, decreased performance, advanced
component failure, and the risk of fire.
14. The unit is intended for indoor use only. Out-
door use will cause a decrease in performance,
advanced component failure and the risk of fire.
This section applies to all Everest products. Correct installation ensures proper performance
and longevity of your appliance. Professional installation by a trained refrigeration technician
and electrician is recommended. Warranty is void if the following guidelines are not met.

Installation Instructions
Shelf Installation
1. Attach the shelf clips onto the pilasters by inserting its
top hook into a pilaster notch followed by the bottom
hook. Do not use pliers or other crimping tools to
modify the shape of the shelf clips. This will result in
shelf mounting instability.
2. Place shelves on the shelf clips making sure all
corners are mounted securely and evenly with identical
distance from the unit’s floor and up. Always lay the
back of each shelf down on the rear clips before the
front.
3. When removing a shelf, unmount the shelf from the
shelf clips. To detach the shelf clip from the pilaster,
tilt up the shelf clip until the bottom hook clears,
followed by the top hook.

Electrical Safety
Everest units come as 115 volts, 60 hertz,
single phase.
Everest units in this family are equipped with a
NEMA 5-15P. A 15 amp breaker must be used
for units that come with a NEMA 5-15P plug.
The ground prong must not be removed to reduce
the risk of electric shock and related hazards.
If the grounding pin is missing, the cord must
be removed from use. If the outlet is a standard
2-prong outlet, it must be replaced with the
properly grounded 3-prong wall outlet. Only
a qualified electrician may install the correct
power source.
To guarantee electrical safety, the wall outlet and
circuit must be checked by a qualified electrician
to make sure it is properly grounded.
Remove debris from the power plug prongs
with a soft cloth or brush before connecting
it to an outlet.
Assign the unit to a dedicated, undamaged
electrical circuit with a voltage rating that
matches the data plate. Check the incoming
voltage with a multi-meter. This avoids the
overloading and overheating of circuit wires
which may lead to a fire.
Do not use extension cords, adapter plugs or
other third party electrical connections. Everest is
not responsible for issues resulting from improper
electrical connections, electrical power failures
and voltage fluctuations.
Everest does not recommend the use of
generators in conjunction with the unit due
to voltage fluctuations that may compromise
electrical components.
Turn off the unit using the power button before
unplugging. Wait at least 5 minutes before
re-plugging to prevent damage to the compressor.
Do not unplug the unit by tugging on the power
cord. Grip the plug and pull it securely out of the
outlet.
Prevent damage to the power cord by providing
sufficient clearance around and under the unit.
Do not use a power cord that shows cracks or
exposed wires. Power cords that have been
severely worn or damaged must be replaced
with original manufacturer parts and only by
an authorized technician.

Operation
Operation
Use your Everest product according to its intended functions. Warranty is void if the following
guidelines are not met.
Starting your Everest Product
After plugging in the unit, the current temperature and compressor symbol will appear on the
digital temperature control’s LED display. will flash at short intervals for 1 minute after which the
compressor(s) and condenser fan motor(s) will initiate. At the beginning of every compressor cycle,
the condenser fan motor is automated to rotate in reverse for 30 seconds in order to blow dust off the
condenser coil.
The evaporator fan motor(s) will initiate once the evaporator coil reaches a specific temperature
relative to the digital temperature control setting and for as long as the door is closed. A fan symbol
will appear on the LED display to indicate that the evaporator fan is running.
Allow the unit to operate for 24 to 72 hours before storing contents in the cabinet. This lets the cabinet
temperature fully stabilize. Use this time to verify proper installation and operation.
The interior light and evaporator fan motor is controlled by a door switch for door models.
The default temperature setting is 35.0°F (2.0°C) for refrigerators and -4.0°F (-20.0°C) for freezers.
The factory recommended temperature range is between 33.0°F (1.0°C) to 40.0°F (4.0°C) for
refrigerators and -5.0°F (-21.0°C) to 0°F (-18.0°C) for freezers. Setting the temperature outside of the
recommended range will cause performance issues and in some cases may result in component failure
that is outside of warranty coverage.
The compressor, condenser and evaporator fan motors run while the unit is on refrigeration cycle.
The compressor, condenser and evaporator fan motors stop running while the unit is on defrost cycle.
The unit is preset to defrost every 5-6 hours with a duration of 45 minutes or less depending on the
evaporator coil temperature. Changing the preset outside of the default range will result in cooling
issues and advanced component failure.
The digital temperature control is intended to read and display the cabinet’s air temperature, not actual
food product temperature. The displayed temperature may fluctuate due to frequent or prolonged door
operation. The most conclusive method to determine a unit’s cooling performance is to measure the
food product’s temperature using a digital food thermometer.
